The present invention appertains to new that the invention is adapted tobe attached to and useful improvements in looms and more the loomstructure generally referred to by particularly to a novel attachmentadapted numeral 5and on the battery side thereof. to eliminate jerked-inor trailing filling The attachment includes a bracket 6 se 5 in the weftof conventional looms. Jerkedcured to the loom structure 5 by suitableelein or trailing filling is caused by thefillments 7 and having aprotuberance 8 extending being held by the shuttle in the operation ingoutwardly at its intermediacy.

A. substantiallyU- shaped frame 3% has its leg portions secured to the top and bottom ofthe block 32, and is apertured at its bi ght portion to slidably receivethe stem 35 of a bolt 36, which bolt is slidably disposed through anopening 37 extending transversely through the block 32. A compressiblecoiled spring 38 is interposed between the bight portion of the frameand the bolt 36 for normally maintaining the bolt projected to theposition as shown in Fig. 3. The free end portion of the stem 35 isguided by the guide device 16 and it will be seen that the intermediateportion of the device 16 gradually flares upwardly as at 38 to theshoulder 39, so that as the aforementioned trigger block moves upwardly,the stem will gradually feedto compress the spring 38 and retract thebolt 36.

In Figure 5, the bcadng set 40 is threaded at one end for dispositionwithin a threaded recess in the loom structure 5 while its outer endportion is also threaded to receive the adjusting nut 4-1. A block 42 isprovided on the set 4E0 adjacent the loom structure 5 and is providedwith an angularly disposed face e3 against which the adjacent end of theblock 44; is adapted to wipe when moved. The nut ll is adapted to be fedagainst the washer 45, which in turn compresses the spring elG againstthe movable block 4rd.

The end portion of the spring 46 adjacent tbe block i4: has an extension47 which engages arounl the arm 49. The arm as is bent laterally as at50 and obliquely as at 51 in acute angular relation to the portion 50.A. pin 52 is disposed between the lower end portions of the strap 33 anda block 53 rotatably mounted thereon. A pintle 54 depends from the block53 and is pivotally con nected as at to the rod 56, which rod isthreaded as at 57, its lower end portion.

An angle member 58 is provided with an eye 59 at one end for receivingthe threaded portion 57 of the rod 56 and nut 60 on the threaded portionof the rod 56 serves to ad justably secure the eye 59 at a predeterminedposition on the rod.

The depending portion of the angle member 58 is disposed through theapertured free end of the portion 51 of the arm 49. Thus a swivelledconnection is provided between the arm 4-9 and the rod 56. Theaforementioned block ll is provided with grooveways 61 which receivedthe secured end of the arm l while the other is adapted to receive thesecured end of the arm 62, which arm is provided at its free end withthe serrated filling engageable blade 63. The blade 63 is disposedlaterally for contact with the chute 6d of the bobbin replenishingmechanism.

It will be seen that the downward stroke of the i'ransferrer arm 22 willcause the downward movement of the rod 20 and the slipping by of thepawl 28 past the bolt 36. The tension of the spring l6 will snap thefilling engageable blade 68 against the trailing fil ing where it willremain until the transferrei arm 22 moves upwardly. As the arm travelsupwardly, the pawl 28 engages beneath the outer end of the latch 36 andmoves he trip carrying block upwardly within the guide 14. The pawl 28will remain abutting the bolt 36, until the slotted end portion of thestem 35 has been moved sufficiently by the inclined disposition of theportion 38 of the device 16 so as to disengage the bolt 36 from the pawl28.

The trip will then descend within the guide 14 to the position shown inFigure 4, thus swaying the filling engageable blade against the chute64.

It will thus be seen that the present device is substantially automaticin operation and depends upon movements of the transferrer arm or someother similar operating feature of the loom, and it is to be furtherunderstood that this attachment may be connected to various types oflooms, various changes in the specific shape, size and materials may beresorted to without departing from the spirit and scope of the inventionas claimed hereinafter.

Having thus described my invention, what I claim as new is:

1. A machine for looms comprising a filling engageable arm, a tripmechanism, means interposed between the trip mechanism and the usualtransferrer arm of the bobbin replenisher, and a connection between thetrip mechanism and the said filling engageable arm whereby the arm maybe moved to enthe trailing filling and be released by said tripmechanism after a time interval suflicient to break the filling, saidtrip mechanism consisting of a spring projected plungand means forengaging the plunger to retract the same when the same is belng moved ina predetermined position.

2. A machine for looms comprising in com bination, a bobbin transferringmechanism, a filling engageable arm, a trip mechanism, said tripmechanism including a pawl, a rod depending from the usual transferrerarm of the bobbin mechanism, a spring projected bolt, a connectionbetween the projected bolt and the filling engageable arm, and means fordisengaging the said spring projected bolt from the pawl upon apredetermined movement thereof responsive to the operation of .thetransferrer arm.
